ADJUSTABLE CRADLE FOR VEFTeREPLENl-.SHING LOIVIS.

Application led May Il,

This invention relates to improvements in the construction ot cradlestor wett replenishing' looms ot the multi-color type and an object otthe invention is to provide a cradle ot variable length to be used withlong or short bobbins.

A further object ot the invention is to provide a multi-part bobbincradle having two sections which slidably interengage with each otherand are held together by removable means which permit relativeadjustment to lengthen or shorten the cradle.

1With these and other objects in view which will appear as thedescription proceeds, my invention resides in the combination andarrangement ot parts hereinafter described and set iorth in the claims.

ln the accompanying drawings wherein I have shown a convenientembodiment o'l' my invention,

Fig. 1 shows the inner and outer plates ci a 1nulti-color wettreplenishing` mechanism provided with my improved cradle and indicateshow the outer plate can be adjusted 'for different lengths of hobbins,

Fig'. 2 is a `perspective view of my improved cradle,

Fig. 3 is a fragmentary `liront elevation ot the adjustable portionsolthe cradle,

Fig. 4L shows one end of the section which engages the butt ot thebobbin,

Fin'. 5 is a view similar to Fig'. 4 but showing' the end portion whichengages the tip of the hobbin, and

Figs. 6 and 7 are vertical sections on lines 6-6 and -7 ot Fig. 3.respectively.

Referring' more particularly to the drawings it will be seen that l haveprovided a magazine oit' the multi-color type such as is set forth inprior Patent No. 1.030.748 and having an inner plate 10 provided with aplurality ot vertical ,sruideways for the heads ot the bobbins andhaving another plate 11 also provided with guideways for the tips of thebobbins. The guideways separate the bobbins into vertical stacksaccording' to color, the bobbins being moved downwardly one at a time totransfer position. At the bottom of each stack of bobbins is located asocalled cradle 12 which acts as a gate to pass one bobbin at atime fromthe stacks to the yielding` IDriveways 13 such as those shown in PatentsNo. 1,366.95() and No. 1,495,717. In the normal operation ot thercplenishing 1925. serial No. 27,638.

mechanism the cradle is empty and at indication ot wett exhaustion bythe wett detector the cradle is rocked to receive a bobbin. When theindicating` shuttle returns to the magazine side ot' the loom the cradleis `given a return movement to its normal position and discharges thebobbin. The plate 11 is adj ustably mounted on tie rods 14 extending?,`from plate 10 and can be moved on said roc toward or from said plate 10.

It is occasionally desirable to vary the length or the bobbin used in aleoni and under these conditions it has heretofore been necessary totake out the old cradles and insert an entirely new set. This changeinvolves adjustment ot the ends ot the new cradles and alsonecessitates: two complete sets of cradles. in order to avoid thesettings and adjustments necessary when new cradles are inserted in themagazine and also to avoid the necessity tor liaving` an extra set otcradles l propose to make each cradle in two sections which shall haveinterengragina portions to permit the length of the cradle to be varied.

Accordingly in carrying out my invention l provide two cradle sections20 and 21 which engage the butt and tip. respectively of the boobins.The section 2O has a bobbin supporting linger 22. bearing' 23, and a pin211hy means ot which the cradle is oscillated. rlhe section 21 is alsoprovided with a bea-rim;l 25 and has a. nose 26 which engages the tip otthe bobbin to regulate the movement of the same toward transferposition. The section 2O has the end 27 thereoiZ provided with a tongue28 which extends to that end of the section 20 remote from the bearing;`23. The section 21 is provided with a .groove 29 proportioned to litsnugly over the tongue 23. The tongue 28 and `groove 29 aresubstantially parallel to the axis ot the cradle. A slot 30 extendslongitudinally ot the section 21 and is proportioned to receiveholding.` screws 31 which extend through the slot into tapped holes 32in the tongue 23 to hold the two sections together firmly.

The cradle is shown in its ,rrreatesfit length. in the drawings and whenit is desired to shorten the same the screws 31 can be loosened andfitted into the proper threaded. holes 32 and the sections adjusteduntil the desired length is ohtiu'neca ail'ter which the screws 31 canbe tightened.

Fig.. 6- shows the portion oi section il() which Iis adjacent the bobbinto be concave as at/SS and the section 2i extends in frontV for alladjusted positions thereof'.

From the foregoing it will be ecn that I have provided an adjustablecradle jformed oi' two sect-ions with overlapping Vportions which can besecurely fastened together to be used with bobbins of various lengths.It will also be seen that when the ends of the cradle are adjusted forany particular niagazine frame they can be used for ditierent lengths ofbobbins wit-bont requiring new adjustments when a different length oibohbin is used. It will further be noted that the tongue and grooveconnection between the sections maintains the sai-ne angular position ofthe ends ot the section for all adjusted lengths thereof.

Having thus ydescribed my invention it will be apparrent that changesand modilications may bemade therein by those slilled in the art withoutdeparting from the spirit and scope ci the invention, and I do not wishto bel limited to the details herein disclosed but what I claim is:

i. In a bobbin replenishin-g mechanism for looms, an inner plate for theheads oi bobbins, an outer plate for the tips oft bobbins, means to holdsaid plates in adjusted spaced relationship, means formed on said platesdeining a guideway for bobbins, and a discharge device located at thebottom oi the guidevvay and supported by said plates andextendingtherebetween and iormed of two parts, one for the heads and onefor the tips of the bobbins, said parte being held together in any oneof a. plurality of positions to render the device capable ot assumingy aplurality of lengtlfis depending upon the distance between said plates.

2. In Ya bobbin replenishing mechanism for looms, an inner plate fixedwith respect to the loom, an outer plate adj ustal'aly spaced from theinner plate, means formed with said plates defining a guideway for thebobbins', and an extensible discharge device located at the bottom ofthe guideway formed of two parts, one for the heads and one for the tipsof the bobbins, said parts being held together in any one oit apluralityot positions to render the device capable of assuming ka plurality oilengths depending upon the adjusted distance between said plates. Y

3. In a bobbin replenishing mechanism tor looms, a fixed inner plate, anouter plate, Vmeans extending` between said plates to space the same inadjusted positions, meansA carried by said plates defining a guidewayfor the bobbins, and an extensible discl'iarge device located at thelowerl end of the guideway, and having a part tol engage the heads andanother part to engage the tips ci the bobbins, said parts beingcon-nectable together in diiierent positions to render the device oivariable length to extend between the plates in all adjusted p tionsthereof.

el. A loom weit replenis-hing mechanism cradle formed in two partsslidable on each other, complementarily ori'ned guide means onsaidparts, and means tohold said parts together in adjusted position, one oisaid paits being formed to receive the butt ot a bobbin and the otherpart being formed to receive the tip ot a bobbin.

5i. A loom wett replenishin'g mechanism cradle formed in two parts, onevof said parts having a rib substantially parallel to the axis of thecradle and the other part ha 7ing a. eoniplementarily formed slot toreceive the rib, said slot also being substantially parallel to the axisof the cradle,` and means to secure said parts together in adjustedlongitudinal position.

6. A loom weft replenisliing mechanism cradle having' two part-s, onepart formed to act on the tip oi a bobbin and the other` part formed toact on the butt oi a bobbin, said parts having overlapping portions andadjustable connections extending through the overlapping portions tohold the parts together in any one of a plurality of positions.V

7. A loom weft replenishing mechanism cradle having two parts. one partformed to act on the tip ot a bobbin and the other partl formed to acton the butt oi a bobbin,

Vand means to secure said Vparts together in any one of a plurality cilongitudinally adjusted positions, said means preserving the samerelative angular position with respect to said parts for alllongitudinally adjusted positions thereof.

In testimony whereof I have hereunto afiiXed my signature.
